Located at the north end of Battery Park City, at the corners of River Terrace and Warren Streets, Rockefeller Park features a playground, gardens, and a wide, grassy lawn with beautiful views of the Hudson River. The River To River Festival at Rockefeller Park/BPC concerts take place Wednesday evenings in June and July. There’s plenty of room to stand, set up a lawn chair, or spread out a blanket. All events in Rockefeller Park are free.
